ds4_driver

Language grade: Python

DualShock 4 driver for ROS.

Features

  • Get information such as IMU, battery, and touchpad from your DualShock 4.
  • Use feedback such as rumble, LED color, and LED flash via ROS topics.
  • Connect to your controller via Bluetooth.
  • Utility node included to publish velocity commands from inputs

Installation and Usage

This driver depends on ds4drv. Some features of this driver depend on pull requests have not yet been merged upstream. Until they are merged, use naoki-mizuno/ds4drv (devel branch).

$ git clone https://github.com/naoki-mizuno/ds4drv --branch devel
$ cd ds4drv
$ python2 setup.py install --prefix ~/.local
$ sudo cp 50-ds4drv.rules /etc/udev/rules.d/
$ sudo udevadm control --reload-rules
$ sudo udevadm trigger

Compile and source this package just like any other ROS package. To run,

$ roslaunch ds4_driver ds4_driver.launch
# Or
$ rosrun ds4_driver ds4_driver_node.py

Disable touchpad input device

Note: You can skip this section if you use the forked version of ds4drv (i.e. naoki-mizuno/ds4drv) because the following line is included in the udev rules by default.

By default the touchpad of the DualShock 4 is recognized as an input device. Because of this, the mouse moves to the location on screen that corresponds to the location touched, making it very hard to track the mouse cursor (and worse, it automatically clicks at that location). If you want to prevent the touchpad from being recognized as an input device, add the following to the udev rules and run the udevadm commands (you will still be able to use the touchpad from this driver):

SUBSYSTEM=="input", ATTRS{name}=="*Wireless Controller Touchpad", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

Demonstration

Get a glimpse of some of the features of ds4_driver including touchpad, rumble, and LED control:

$ roslaunch ds4_driver demo.launch

Moving the left/right stick controls the rumble. Sliding left and right on the touchpad while pressing circle, triangle, cross buttons controls the brightness of the red, green, blue LED, respectively (you can tell from the color of the button). Pressing the PS button triggers the flashing of the LED.

ds4_driver_node.py

This is the main node that interacts with DualShock 4.

Parameters

  • ~device_addr: hardware address of the device. If unspecified, will use the first device found.
  • ~backend (default: hidraw): what backend to use to connect to the device via Bluetooth. bluetooth is only there for legacy support and has not been tested. Refer to the docs in ds4drv for details.
  • ~use_standard_msgs (default: false): use ROS-standard messages such as sensor_msgs/Joy.
  • ~pub_joy_on_change (default: true): only publish Joy messages when changes to axes or buttons is detected. This parameter is only effective when use_standard_msgs is true.
  • ~deadzone (default: 0.1): amount by which the joystick has to move before it is considered to be off-center.
  • ~frame_id: (default: ds4): frame ID to be used for the messages.
  • ~imu_frame_id (default: ds4_imu): frame ID to be used for the IMU messages.

Topics

Published

  • /status (ds4_driver/Status): current state of the device.

Subscribed

  • /set_feedback (ds4_driver/Feedback): feedback for the device such as LED color, rumble, and LED flash.

Note: To disable flash, send message with set_led_flash: true and led_flash_off: 0.

Topics (when use_standard_msgs is true)

Published

  • /raw_report (ds4_driver/Report): raw, uninterpreted report that the device sends.
  • /battery (sensor_msgs/BatteryState): battery state of the device.
  • /joy (sensor_msgs/Joy): joypad state.
  • /imu (sensor_msgs/Imu): IMU state.

Subscribed

  • /set_feedback (sensor_msgs/JoyFeedbackArray): feedback for the device.

ds4_twist_node.py

A node to convert joypad inputs to velocity commands is included in this package. This node is something similar to teleop_twist_joy but is specifically for a DualShock 4.

Parameters

  • ~stamped (default: false): whether to publish Twist or TwistStamped for the output velocity command. For robots such as TurtleBot, Husky, and PR2 /cmd_vel is not stamped (i.e. Twist is used) but stamped velocity commands may be required for some applications.
  • ~inputs: what buttons and axes to use for the value of each velocity vector. Expressions can be used to combine values of multiple keys (see config/twist_6dof.yaml for examples).
  • ~scales: scaling factor for each velocity vector.

Topics

Published

  • /cmd_vel (geometry_msgs/Twist or geometry_msgs/TwistStamped): velocity command.

Subscribed

  • /status (ds4_driver/Status): joypad state.
